o iNG, VARREN A. PARKER, and ROBERT HUGHES, citizens of the United States, residing at Minneapolis, iii the county of Hennepin and State ,of Minnesota, have invented certain new and useful Improvements in Dump-Cars; and we do hereby declare the following to be a fullclear, and exact descri ption of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to lateral motion dumping cars, suoli as used on railroads and elsewhere for conve ring dirt and dumping the same at the sid of the track. To the above ends the invention consists of the novel devices and combinations of devices hereinafter v described and defined in the claims.

Dumping cars of the character above indicated are rovided. with. displaceable side boards andpwith devices whereby the side board on fthe, lowered side of the pivotally supported car body will be moved into an inoperative position, -so as to permit the disc arge of dirt under the action of gravity. Dirt dumped with cars ofA this kind, as hitherto constructed, will be piled up close to the track and run under the wheels of the car, so that it is impossible to move the car until` after a large amount ot dirt has been shoveled oit from the track, so as to aord clearance for the wheels.

Our invention provides a simple and eifie cient device which prevents the dirt from piling up under the wheels of the car, and this is accomplished by providing the pivoted car body, at each side, with a depending guard board and by providing the truck trame with deflecting guides that operate upon the guard board at the lowered side of the car body to hold the same in such position. that the dumped load of dirt cannot` possibly run under the wheels or onto the track.

in the accompanying drawings which illus-` ing a car having body pivoted for lateral dumping movements, and illustrating our in- ;.ition applied to the said ear; and Fig. 2 is diagrammatic side elevation, with vsome -dotted lines 'ii' Fig. l.

parts removed, showing particularly the ni'annei' in which the guard board guiding devices are secured to the side frames of the carl truck.

dumping movements to the truck frame 5 in the usual way. To the. lower edge ofeach side of the bottom of the Abody or box 6 are hinged depending guard boards 8, to the inner sides of which'looped metal bearing lugs 9 are secured. i

To the trussed side frames L and to each journal boX is secured a deiiecting guide, preferably formed by curved metal straps 10 having laterally bent inner ends 11 that are rigidly secured to the trussed side frames and to the journal boxes, by the usual column bolts l2. These defiecting guides 10 are so positioned that they will be engaged by the guide lugs 9 of the guard boards 8 whenever one or the other of the said guard boards is lowered byV a downward movement of that side of the box 6 to which the said lowered guard board is ivted. When, for instance, the car boXA or ody 6 is moved from its normal'orv horizontal osition shown by full lines in Fig. 1 into its oblique or dumping position shown by dotted lines in Fig. 1, the guide lugs 9 o n the lowered guard board will run down- 10 and will cause the lowered guard board to be'swung slightly outward and upward, approximately into the position shown 'by In this lowered or dotted line position the guardboard constitutes a sort of extension of the bottom of the carbox and 'serves to carry the dum ed load of dirt ,fartheraway from the whees ofthe Vcar'truck than vif the said deiiecting board Y and cooperating or stop devices. werel not provided'. Furthermore, the said deflecting board positively prevents the dumped load of dirt from running inward onto the track and against or between the wheels of the car trucki Y The device above described therefore, as is evident, preventsv clogging of the track and effects a very great saving in time and labor. In yactual practice the said device has been vward over the coperating deilecting guides found highly efficient for the purposes had in view.

What we claim is:

1. The combination with a car having a body centrally pivoted for lateral dumping movements in either direction, of guard boards hinged to. and depending from the outer edges of the bottom of said body, and means carried by the truck arranged to limit the dumping movement of said oar body and the ihward swinging movement of said uard board von the lowered side of said eer ody, whereby the dumped load of dirt is prevented from running onto the track, substantially as described.

The combination with e ear having a l said body, and defleeting guides secured to theside frames of the truck of said. ear and arranged to swing outward and hold the defiecting board on the lowered side of the boX,

whereby the dumped load of dirt is prevented from running onto the track, substantially as described.

3. The combination with a ear having a body pivoted for lateral dumping movements, of guard boards 8 hinged to the edO'esof the opposite sides ofthe bottom of saidzbody and provided With bearing lugs 9, of guides in the form of metal straps 10 having laterally bent ends 1 1 bolted to the side frames and ournel boxes of the truck of said oar, -the guide stri s 10 bein 'loeated for engagement with sai bearing ugs 9 and being arranged to swing and hold outward the guard board on the dum ing side of theear, substantially as describe In testimony whereof We aHiX our signatures in presence 'of twowitnesses.
